It is sized and shaped for popular 1/10-scale radiosteered car models, with a toothed gear gear and a cylindrical housing marked by contrasting circumferential bands that make it easy to identify. As a central drivetrain component, this differential gear plays a role in how power reaches the tires It works alongside a separate bevel gear included with the assembly to split rotational force between the two output sides, allowing the outer wheel to rotate faster than the inner wheel through corners for more controlled handling and less tire scrub. Built from alloy, this gear assembly combines strength with relatively low weight, so it can stand up to repeated forward motion, braking, and impact loads without adding unnecessary mass to the chassis. Silver-colored bearing collars and black forked output complete the construction, giving you a clean, serviceable design that mates cleanly with axles and bearings on compatible cars. Installation is straightforward on supported base units, including TT02, XV02, MB01, BT01, and XM01 chassis. Because it is supplied as a complete assembly in a bag, you can install it into your car without sourcing individual separately, making it ideal for both planned maintenance and unexpected breakdowns at the trackside in the workshop. Since it is a manually operated, non-electric part, this 39-tooth differential gear assembly focuses purely on dependable mechanical performance. It promotes smoother power transfer and more consistent drivetrain behavior, so your car accelerates predictably, corners with better stability, and holds up reliably run after run.\n\nOption: Red","category":{"slug":"hobbies","label":"Hobbies & Collectibles","google_path":"Vehicles & Parts > Vehicle Parts & Accessories > Motor Vehicle Parts"},"product_category":"Vehicles & Parts > Vehicle Parts & Accessories > Motor Vehicle Parts","brand":"SuntekStore","condition":"new","price":"33.59 USD","price_amount":"33.59","currency":"USD","price_valid_until":"2026-10-31","tax":"US sales tax calculated at checkout (prices exclude tax)","availability":"in_stock","inventory_quantity":20,"max_quantity_per_order":10,"shipping":"US:ALL:Standard Shipping:12-22:0.00 USD","delivery_days":{"min":12,"max":22,"unit":"calendar_days_from_order","handling_business_days_max":4},"estimated_delivery":{"if_ordered_on":"2026-10-01","earliest":"2026-10-13","latest":"2026-10-23"},"ships_to":["US"],"shipping_cost":"0.00 USD","return_window_days":30,"return_policy":{"window_days":30,"window_starts":"delivery","condition":"unused, in original packaging","return_shipping_paid_by":"customer (we pay if the item is damaged, defective or not as described)","refund_method":"original payment method","refund_within_business_days_of_receipt":5,"how":"https://suntekstore.com/contact/ with the order number","url":"https://suntekstore.com/returns/"},"package_dimensions_cm":[17.0,16.0,5.0],"weight_g":90.0,"material":"Alloy","package_includes":"Differential Gear ×1","product_dimensions_cm":[3.96,1.58,6.1],"specifications":[{"name":"Tooth count","value":"39 tooth count"},{"name":"Scale","value":"1/10"},{"feature":"Manual, non-electric"},{"name":"Compatible base units","value":"TT02, XV02, MB01, BT01, XM01"},{"name":"Features","value":"Toothed metal gear gear, cylindrical housing, silver-colored bearing collars, black forked output"}],"image_link":"https://suntekstore-img.sfo3.digitaloceanspaces.com/p/2c/2c9c0ccd5954c0ee22308c8107dc0025f92de135.jpg","additional_image_link":["https://suntekstore-img.sfo3.digitaloceanspaces.com/p/42/42b2dc4046aea7cc365fea882c5fc2fff062ca6d.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/f9/f935f9719c6025eb0b7863fc870e51893a39b7b2.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/39/39460dbc41117b0b1286af309a96afe02cae1fdf.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/c8/c89b46f39b546b97d8293e937a41be0290976d26.jpg"],"thumbnail_link":null,"link":"https://suntekstore.com/p/DCD-10001510376/","markdown_url":"https://suntekstore.com/p/DCD-10001510376.md","json_url":"https://suntekstore.com/products/DCD-10001510376.json","buy_url":"https://suntekstore.com/buy/DCD-10001510376?qty=1","prop65_warning":null}
